World’s Smallest Microphone

Wait, wait, what you’ve already seen from the image isn’t the world’s smallest microphone we’re here to argue. Actually, the smallest capacitor microphone built by Noshirvani University of Technology researcher Bahram Azizollah Ganji is merely 0.5 X 0.5 mm big, almost invisible to the naked eyes. However, it comes with really high sensitivity and low power consumption, and can be widely used for a variety of purposes such as diagnosis of cardiac problems or marine surveillance.
